IMPROVED GAS-GOVERNOR.

Specification forming part of Letters Patent No. 77,572, dated May 5, 1868.

ernor; and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appert-ains to make and use my said invention or improvement without further invention or experiment.

My invention relates to gas-governors of that class in which a diaphragm is acted on by the pressure of the gas, and its nature is the use of a thin metallic diaphragm which shall not be pervious to or be acted upon by the gas. It also consists in connecting this diaphragm with a valve by means of a series of levers, so that the supply for the burners shall be regular and equal. By means of a weight upon one of the levers, operated by a rod passing through a stuffing-box from the outside, the pressure is regulated for the greatest number of burners to be used, while the valve and diaphragm regulate the amount for any less number.-

In the drawings forming a part of this specification, Figure 1 is a side sectional elevation of my governor, showing the position of the parts. Fig. 2 is a plan of the top of the case and the diaphragm.

Similar letters of reference in each of the figures indicate like parts.

A is a case,of any convenient shape and size, having its top B composed of thin metal. I use tin-foil, as being easily fitted, and it may be attached to the rim a by shellac. A red or post, 0, passes through the center of the diaphragm B, having a washer, D, below, and a plate, E, above, the whole being held by the nut F. The lever G has its long arm attached to the side of the caseA at H, where it moves slightly on a pin. This lever passes through the bottom of the post 0, being attached by a pin, and has the end of its short arm connected with the lever I by the connecting-bar J. The lever I has its fulcrum supported by the post K. The power is applied through the connecting-bar J,while the end L has the valve M attached to'it, both G and I being levers of the third class, and so made that the valve M rises a greater distance than the diaphragm moves.

est number of burners used.

The valve is made conical in form, and has a seat, N, made of hard leather, into which it fits when closed.

The gas is admitted from the meter through the ingress-pipe O, and the transverse chamber P beneath the case A. From this it passes .into the case A when the valveM is open, and

enters the service-pipe at B). A sliding weight, S, is placed on the lever G. This weight is moved back and forward by the rod T, which moves through a stuffing-box, U, thus preventing leakage. The weight Sis moved along the lever to apoint where the pressure of the gas, by its action on the diaphragm B,will keep the valve M so opened as to just supply the great- If any or nearly all are shut off, the pressure will increase and raise the diaphragm B. This acts on the levers G and I so as to raise the valve M and partially close the opening. A counterpoise, V, is attached to the leverI at W, to balance the valve M. The post 1) guides the lever I, so that the motion of the valve M will be exact. A bent lever, 0, is pivoted to astandard, d, so that one end is directly beneath the end L of the lever Lwhile the other end curves over the top of the lever, and has fastened to itaweight, g. A link, b, attached to the lever end of the diaphragm, communicates motion to .thelever c. When this lever and weight are in the position shown at Fig. 3, the valve M is fully open; but as the valve closes their weight is brought more directly over the standard (1, and

the weight is less. In this wayit equalizes the pressure when a large number of burners are in use. It also assists in moving the valve M when closed, and prevents its sticking.

By using a metallic diaphragm I am enabled to make it extremely delicate and thin Without the danger from leakage that would occur if parchment or leather were used, and it is easily renewed at any time in a few minutes.

By means of thesystem of levers G'and I and the sliding weight S the valve is instantly acted upon by any change of pressure, and the amount to be admitted is determined and regulated with certainty, and the trouble experienced'from the change of pressurein the mains or resulting from the increased pressure caused by turning off a part of the lights is avoided. It is also a great saving in gasbills.

Having thus described my invention, whatI I 3.
